There was also a report of a
family with both PJS and polycystic kidneys, though I couldn't tell from the
title whether the two conditions were linked or coexisted. (3)

Another patient with PJS
& kidney cancer is reported by Linos of Mayo Clinic in 1981. The abstract
of this very odd article concludes, "During the 45-year period between
1935 and 1979, 48 patients with Peutz-Jeghers syndrome were

seen at the Mayo Clinic,
Rochester, Minn, and followed up for a median period of 33 years. Carcinoma of
the small or large intestine did not develop in any patient, with possibly one
exception." While the article itself contains the following contradictory
information, "During this 45 year period, carcinomas developed in six of
the 21 patients as follow: lung, two patients; breast, one patient; biliary
tree, one patient; kidney, one patient; and uterus, one patient. One patient
with a previous history of breast cancer and bilateral ovarian cystadenomas was
found to have abdominal carcinomatosis. Pathological examination showed
metastatic grade 1 mucous adenocarcinoma, but it was not possible to determine
whether the primary lesion was of colonic or ovarian origin." (6)
